Wondering what you guys use for your bench supplies, My 750W is like 6 years old and I might be looking at swapping it out soon!

My main benching table has a 1500 watt Enermax But for some of the older boards like the NF7X that I ran the other day I was using a 620 watt Antec Neo with a modded 3.3 volt rail I was running it at 3.5v the other day.

Got a 1000w Antec CP series with upgraded fan. But if benching for hard core, the more wattage + quality the better.
Mines old but still kicks butt.

95% of my benching is done on a 10 year old Turbo Cool 1200.

if it's just CPU, my old Ultra 750w PSU does the trick. Single/Double GPU I'll pair the Ultra 750W with an Antec 750W. I'll tie a few of the black's together to make both GPU's the same potential difference, I have a jumper for the green wire on the 24pin.
the Ultra does the MB and the Antec does the GPU's
I've always benched on the cheap (when I was benching) Vin

I've been rather fortunate in the PSU dept, my main bench PSU for the past 12 months or so has been a Corsair HX1200i but I have 2 x AX1200i if I need the extra. Used to have a Silverstone 1200w before all those which lasted me a very long time before I retired it to a gaming rig.

Ahh, I see really seems like 1000-1100W would make the most sense for me or a second 750w to run just the gpu's although it's preferable to have a single

Rosewill Hercules 1600W here as the main PSU to run, also have an old PC Power and Cooling 750W "Silencer" single rail and a 650W Corsair unit for some of my older stuff.

I think I'm going to grab a 1600W Lepa gold rated for benching, I think Enermax made those so shouldn't be complete garbage

I'd let one of the others chime in before pulling the trigger. As far as I know that's not a bad PSU but may be a better unit you could get too.

It's a very good unit but overkill. A good 1200w unit will run anything you throw at it, for less money. Personally, I would get a 1000w Seasonic Focus for $150 and call it a day.

Concerning a PSU I woudn't trust an open box unit - There was a reason it got sent back and you don't want to find out why the hard and expensive way. Could be it's OK but I just woudn't chance it.

I need 2 X Corsair AX 1600i ( 133A on the 12 Volt line EACH ). One feeds I9-7980XE running 5.3ghz on DICE and the second 2 X RTX 2080 TI.
Not even an 8Pack 2000W PSU ( Superflower - Leadek ) can hold all these and shuts down.
extremes running the same setup ( LN2 ) use 4000 Watts ( 2 X 8Pack PSU's ).
Power draw on 60A dedicated lines at the wall shows at peak usage 2300-2600 watts.

I do agree George. I was meaning the average bencher. You are on the extreme end my friend. There are always a few exceptions.

Post by ShrimpBrime on Aug 13, 2019 17:51:02 GMT -5
Dang... I thought 1000w was extreme. 2 x 8 packs PSUs?
Might as well run 4 car batteries and 1 aught cables instead. Hamster wheel with belt pulley to an alternator and all set!!
wonder if anyone's tried that yet... hehe.

High end computer PSU's are designed to respond ultra fast to current demands, transient current and speeds up and downs, while maintaining stability on all three rails ( 12, 3.3 , 5V ).
Even the most modern car electricity system, has a primary goal of stability around the 14.4V, even under the heavier demand, the easy startup ( high amperage for start ) and long life expectancy ( 5-6 years ).
Totally different needs.

So what you're telling me is quad SLI PSUs should be a thing 😂

It depends what kind of cards and what processor.
If it is an I7-8700K running at 7ghz and 4 X HD6970 X-fire on Apex X, a good 1200W PSU is enough.
On the other end :
An I9-7980XE running at 5.8-5.9ghz, with 4 X 1080Ti, then YES, 2 X 8Pack psu's ( 2000W each ) are a must.
Simply put - It is what the components draw at their max performance and what should be given to them to remain stable.

8Pack 2000w PSU for the high power draw stuff and an 850w CoolerMaster PSU for everything else.

About 99% of my benching is done on a 1000w class Seasonic but do have a 1200w Seasonic for the remaining 1% to use in tandem, don't push as hard as George. Also have a Antec 500w unit that I still use from the Athlon XP days. So if it will run a stock quad VGA setup without problem probably not a bad starting point always nice to have a little extra in reserve.

I got a small collection building up: For now I use just the one P2 1600, but when I need more juice I´ll have some back-up. I mainly ended up with 4x 1600W PSUs because I got them so cheap. On average I paid 150€ per unit... 2 of those are new, two are used.

Post by Vinster on Dec 22, 2019 2:48:50 GMT -5
whoa that's a lot of juice there... 1600W... and x4... I couldn't even imagine needing that much.. Wow..
I do have a EVGA SuperNova 1300W G2 in my main rig (1700X with 1080Ti and r9-290x all OC'd a little)

Without subzero gpus or quad sli I can't really see going over 1000w I currently bench with a 430 watt psu

I haven't upgraded PSU's in ages. Still benching on a PCP&C 750 and a TurboCool 1200. Seasonic has been a very good brand for me. I blew up a newer Enermax 1300 in less than a year.

I don´t think I would cool that with my ambient water setup, but who knows.

I'm still benching with a Corsair GS700, because a decent 1000W psu is still $200+ CAD depending on the week. I'm thinking though that next time I upgrade my gaming rig, that I'll give it a new power supply, then move my old evga 1000W G2 to the benching rig.
It'll be nice to have a power supply that can do both cpu 8 pins as well as run mid-tier cards in SLI/Crossfire...

Nothing special here either.. A nearly 10 year old coolermaster 850 that I got from my brother. Its actually pretty decent, better than my old tx850 and the thermaltake 850 I have in my x58 by far. Its runs cool and I can barely make the rails move, unlike my other 850s The other two run cool, but they lost their mojo.
