My PSU recently died, I have managed to borrow one but it only has a single pi-e connector. It also has two Molex connectors, so would making one with wires be safe and advisable?
Need a molex to pci-e connector - could I just make one?

Probably easier just to buy one. You can get them for about £4 on the auction place if you need a molex to 8pin. OCUK do a molex to 6pin, but I can't find an 8 pin version.

Also the PSU is a Alphapower ATX-850L, I can't seem to find anything about this PSU online, I'm a bit worried that it is a really cheap PSU and might take out my system.
It sounds like an el cheapo to me. Is it an 850W ? and what are your system specs

Yes is it a 850W, also the PSU apparently cost £100. My specs are 3930k (£420), P9X79 Pro (£190) 16gb memory (£120), HD 4870 1GB, cheap 30GB SSD, 320GB HDD.
I must admit I have never heard of Alphapower. Also a good quality 850W psu would have 4 x pci-e cables. The fact that yours only has 1 is not a good sign.
Can you see the sticker on the side of the psu ? You want to look at the 12v rail and see what the total wattage and amps are. A good quality unit will be able to deliver 800W+ on the 12v rail.
Here is an example -

The 12v rail can deliver 840W and 70A.

2x 24A so that's 576W, also my old decentish 750W toughpower 80+ gold only had one, but I think that was because it was a goodish PSU that was made a bit cheaper.

+3.3v 30A
+12v1 24A

I have a junk alpha power rated at 650 with NO pcie. Wouldn't trust it, even if the rails on the sticker show it capable to run a small system. Only use it to fire up pumps during leak tests.

I have a RMA with Corsair (AX850), so I am not in need of a new PSU, but thanks anyway.

But the thing about PSUs is that if you choose right it will last you multiple systems and you will have the piece of mind that it will not go wrong, and if it does you RMA it.
I think a lot of it also depends on the manufacturer in question. Some like Enermax are very expensive, whereas Superflower who are on par are priced very well.

The AX850 that I have\had was one of the best on the market. Anything that is a Seasonic is very good.

That is trueJust a shame Corsair are now starting to use cheaper oem's.
The AX860i is still very good.
Flextronics are a good oem. I am referring to the lower end Corsair stuff that used to be Seasonic. They now seem to be using cheaper oem's like Greatwall.

To be fair the lower end is no place for Seasonic, lower end as in price \ performance of course.
