I'm surprised at the number of people who replied without actually responding to his question or offering any options. Telling him 2x5770 on a 500w psu is "imminent failure" is laughable.

Haha, exactly, I'm running 2 hd 5850s and a hd 6850 on a 550w corsair atm. Undervolted them to reduce my PSU load a bit and it works great .
You cannot compare a Corsair 550w to an APEX brand.
APEX is junk, period.
Either spend $100 on a PS, or say bye bye to the entire PC in a few days/weeks/months.
I had a Apex 500W, and it craps out when I pull 250w from it.

500W is recommended for a single high-end graphics card. Putting two in a 500W and running 24/7 @ 100% = imminent failure.

On a unrelated side note, I learned the difference between immanent and imminent just now.

5770 isn't high end, it's 108 watts under full load. He'd never even hit 300 watts with 2x5770. The PSU would be running 55-60% load which is fine.

I agree with Mike, that PSU is horrible.

It's the only component beside the GPU that actually matters for 24/7 use.

Spend the extra for a quality one, skimp on the RAM and processor.

He said "cheapest hardware".

That was not the cheapest PSU. That PSU is actually quite good, there were cheaper options.

Those cards run 108 watts max load. With a 45 watt Sempron, two 5770s that's 261 watts (cpu is unlikely to be under full load). Add in the motherboard, ram, HD, 500w is plenty. He'd never even hit 300 watts. You could even run 3x5770 if you wanted to really push it.

Since he said "minimum/cheapest" setup, I'm quite happy with my suggestions. =)

Agreed with cheapest MB, CPU, RAM to support two PCIe slots.  I have three such rigs that when overclocked together draw 850 watts from the socket.  I use a USB stick to hold the linuxcoin OS - you really do not need a hard disk drive.  I use a 600 W power supply for each rig.

I also do not use any cases - better airflow - despite operating against consumer protection laws for electron emissions.

Minimum requirements?

2 PCIe slots.  That's all you need to care about.  It can have 256MB/ram if you want.  Just get the cheapest new (or used) combo of hardware that has 2 PCIe slots.

That PSU is fine.  5770's run at what, 100 watts each?  That's nothing, and the Apex can easily handle it.

I am running two 5830's on an AMD 4000+ from like 2006 and it hashes damn well (311 per card)
so don't worry about CPU speed at all.

I would highly recommend not skimping on your power supply as it could destroy your whole machine. Get a well known brand that has a lot of reviews.

Hi,

I would like to know what kind of motherboard, processor and amount of ram I would need minimum to support mining on 2x5770 cards if anyone has an idea and could give me some hinters.

Power consumption is irrelevant, I am looking for the cheapest hardware that can support the cards ... and that maybe could handle a 3rd card.
