MOST powerful pc supply!!

[Thorin01]

Hello everyone:

I need to buy the most powerful power supply around 65€ becouse I'm going to connect it to a car-audio amplifier.

So that I don't care about other features like connectors, molex, fan noise or anything else, the only requirement is It has to bring at least 52A in 12v wire, but as we know some brands lie a lot about REAL power so I need your advice

Here are my initial thoughts:

FSP RAIDER 650W -----------> 50A
Cooler Master B-700 700W ---> 55A
TACENS RADIX VI 850W -----> 52A
NOX URANO 850W -----------> 70A

opinions?

Out of the four, I'd probably get the Cooler Master. I don't know much, if anything at all about the other three PSU's.

Are you located in the US?

most powerful and that price don't go well together. what do you even want to run on that psu? if it's a rig fitting the budget a corsair builder psu will do you just fine.

A car-audio amplifier, a DbDrive A4 4200.

if it's a rig fitting the budget a corsair builder psu will do you just fine.

I've searched and the only Corsair I can afford is CX600, but the Amperage is too low from the 52A limit I need for the amplifier. I should look for another not so expensive brand.

Why are you running an audio amp for a car off a pc psu and not just connecting it up the right way ie to the battery and earthing it to the body and using a fuse?

It would be cheaper and easier then messing around with a pc psu.

52A? Dayum, that's high... The PCI-E connectors for the GPU usually provide the highest amperage and they're only at 21-25A - Probably best you buy a specific amp for your stereo system...

Old server psu's off ebay are the usual choice for running 12V devices in the house. (look here for more info)

52A is average for a car amp, the big monoblock subwoofer amps can draw several hundred amps. As the supply voltage is low, the current drawn is high, hence the need for 8 awg up to 0 awg power cables. The amplifier itself is mostly made up of a large switch mode supply which converts the 12V DC to AC then increases the voltage via transformers, then rectifies it back to DC to power the rails on the amplifier. (hence the name DC-DC converter)

I presume the intention here is to use the mains as the input and not the car battery? Because you'd be throwing half the PSU away if you intend to just use the 12V DC that the car battery will give you.

Don't get too hung up about the brand. A lot of companies like Corsair or Coolermaster actually contract another company to make the PSU for them. You've a pretty limited amount of companies that actually make the PSU themselves. It means you often get the funny situation where you've two PSU brands that are actually identical under the hood.

My Corsair HX620W is actually a re-branded Seasonic for example.

Also you're going to want a single 12V rail for simplicity's sake.

52A? Dayum, that's high...

Not overly so, it's a power draw of 624W. Something like a standard 750W PSU will probably give you that no problem.

You certainly wouldn't want to get an electric shock from that, lol.

I want to use the car-audio amplifier in my home, and a car battery+home charger is more expensive than a PC PSU

It's high, but all the PSU I've listed up there reach that amps (on theory)

WOW! that's a clever one
£25/28€ for an 1300W power supply! Where is the trick??
