Power Supply ?

**BrokenApe** · 02-10-16, 04:34 PM

Well, time to start assembling a new PC as the core i7 930 rig is getting long in the tooth :P I've decided on a corsair themed setup because, well.. why not *shrug* I like the carbide 540 case but I'm unsure on their power supplies, I figure a good 750/850 will handle a non overclocked system with a single video card but I've heard dissparaging comments on certain series of Corsair power supplies from peeps here.. just don't remember which series.. I'm looking at either the CORSAIR RMx RM750X 750W ATX12V / EPS12V 80 PLUS GOLD Certified Full Modular Power Supply - Newegg.com or perhaps the CORSAIR HXi HX750i CP-9020072-NA 750W ATX12V / EPS12V 80 PLUS PLATINUM Certified Full Modular Power Supply - Newegg.com so I'm hoping to find out that at least a few people here have purchased on or the other and have commentary to share

I think it's the RM series that takes the heat.

I have had my RM1000 (running two 770GTX) for a bit over two years now, and I think it may be the culprit of my crashes (when I have SLI enabled, BF4 will crash almost every time a new map loads and is just about to start). I will be running to Microcenter soon and picking up another one (they are pretty cheap now....100-150, and I won't have to do anything other than plug the already existing cables into the new psu).

Otherwise.....it's done its job.

So the rm series does allright? I can live with that.. doesn't hurt that it's cheaper then then HXi series either but hell if I had to I'd pay a bit more and all

Corsair RM power supplies 650 watts and up are roughly equivalent to Seasonic or Superflower power supplies. Avoid the CX series at all costs. CX series uses cheap capacitors that will blow under moderate overclock.

Figure on a skylake 6600 and at least for now my r9 290 with no oc and a possible video card in the future may just do the rmx 850 for a bit of wiggle room and with the rebate card it's the same price on that anyway as the 750... yep think that's a start

Well.....My RM1000 wasn't the problem. I just replaced it with a refurb. from Microcenter ($120), and I'm still crashing during BF4.

So yes......The RM series psu's have been just fine for me.

I am no means a PC expert.....but found this... BF4: Crashing with Round Loads [Solved] - Video Games - PC Gaming

Hope this helps.

Oh by the way. I am looking to upgrade power supply so i can get a new graphics card. So any suggestions would be nice..

Many thanks

Huh, after some forum surfing it appears there's some memory leakage that happens with SLI setups in Windows 10 only. Remember how when Mantle was first released and it was actually significantly worse for people with 2GB of VRAM because the engine over-allocated? The same thing is happening here. Apparently the game or the drivers are allowing more RAM to be allocated than the SLI setup allows and the values are getting corrupted, probably due to allocating sequential information into two different cards' VRAM.

Nvidia apparently *had* a solution as of driver 355.80 on 8/25/2015. Not sure if it'll still work, but it might be worth rolling back or attempting to apply the hotfix over your newer drivers. GeForce Hotfix driver 355.80

I originally thought it was the SLI drivers, so I diabled SLI, and all seemed better, but still crashed randomly....maybe once in a weekend as opposed to every map/ every other map.

Which led me to give the psu the stink eye. Maybe the card(s) were calling for more power than a faulty psu could supply. So I replaced the psu (Corsair RM1000....got a refurb from Microcenter for $120), and re-enabled SLI. Crashed. Took one of the cards out....crashed. Swapped cards....crashed.

So today I did a clean install of the video drivers and only have the one known "good" card installed. I used the Asus Bios updater tool to make sure the firmware didn't need updating on the video card itself....it said I was up to date. I also went into the device manager, and disabled all of the Nvidia audio drivers.

Overclocking wouldn't be the cause of blowing capacitors. Aside from requiring the system to draw more DC power, which means the system would need to work harder, overclocking would only impact the specific item you are trying to overclock (CPU/Mobo, GPU, etc).
