I just bought an 1100w apevia power supply but it acts as if it's only 300w. My 700w apevia works fine though. What's wrong?

Specs:
Gigabyte ga-970a-d3p
Amd 6300 6-core ~4.2ghz
16gb ripjaw x series
Gtx 750ti oc to Match gtx960
4tb of storage across 3 baracudas
Apevia 700w/1100w 80+ gold cert.

The fact you're using a doorstop as a power supply would be my first answer.



In all seriousness though, what symptoms are you experiencing for you to quantify that it's acting more like a 300w?

Apevia don't make any gold rated power supplies.
They over rate their units by at least 200w
If its a warlock then component quality inside ia better than average.

Why would you buy an 1100w rated supply for a component lists that tops out at 250w or less ??

The only "1100" Apevia PSU I can find would be the Warlock that madmatt mentioned.

While Apevia don't make any "good" PSUs, the Warlock would be better than their other offerings (still not 'good' mind you).

As low loads (like the OP's rig), it should actually perform pretty well.

Don't get me wrong, I wouldn't recommend anybody runs out & buys one., or even the OP continues using it.... but outside of running it in overly warm conditions, or stressing it much, it doesn't appear to be "unsafe" necessarily.

If it performs similarly to the "900W" variant, which is more of an "800w" if you're being kind (750W if you're not), the 1100W unit = 1000W total. Probably has about 80% of that on the 12V rail ....so 65-67A combined.

Thats not even the worse PSU I've seen mentioned on the forum today :lol: But again, that's certainly not a recommendation for it.

Pretty much my thoughts exactly
What i dont understand is thats a $90-100 psu & for $35 he could have simply bought a cx450m which I would ultimately just trust more ,would be way way more efficient & it still has around 200w clear overhead

It fails to power the system if it has more than 2 fans connected as barebones. No daughtercards and no hdd

With just the cup connected it powers on and the leds in both psu and cpu fan flicker like it's barely enough. If I as another fan to the system at all then the whole system dies and doesn't boot. The fans will flicker and twitch when I press the button. But it won't start. I threw my 700w back in and I'm booted now. I'm even doing stress tests and it's performing beautifully

That is odd, but at the same time; Apevia are not known for quality, so may just be a defective unit.

Take it as a blessing; return the "1100W" PSU and get your money back. I would suggest a replacement opposed to continuing to use that (even) lower quality Apevia unit. As MadMatt mentioned, that 1100W sells for like $90-$100?

If that's what you paid for it, you can do much, much better in quality, and a more appropriate wattage for between 1/3 and 1/2 of that (after rebate)

My system needs close to 600w+ and I am going to upgrade from the 750ti to dual cards. Either r9 fury x or gtx 1080ti. I need 1000w if I'm going to do that. That's why I got this 1100w apevia

What system needs 600W? Your current setup? Nowhere even remotely close. 250W MAX.

As for upgrades,
Dual R9 Fury X's are going to put you somewhere around 700W Max,
Dual 1080TI's around 650W Max.

Neither dual card setups are going to get close to "max" paired with the FX-6300, so I assume you're upgrading that too?
Neither the highest end Ryzen, or Intel I7-7700K are going to increase the 95W TDP requirements of the FX-6300, so not real additional power draw there either.

Older hardware was generally more power hungry. Poor chips exist (see the 225W FX9590 that was pointless), some users would 3-4+ SLI /CFx etc.

A quality 450W unit is usually sufficient for most users today with a single card, 650W for dual. If the PSU is poor quality, or the cards are a little dated..... you'll want to have much more headroom.

Some really cheap "1000W" units can do about 600W stable. So, in that instance there's absolutely no reason to buy. A quality 600W unit could do the same thing, and actually perform within it's efficiency numbers.


I guess finally, there's the "bragging rights" for the 'average' user ..... ie "my PSU is 1000W Gold, yours is only 450W Bronze". When in actuality, the 450W could be the superior quality unit
