Re: Please Recommend a UPS for Z420

Can you provide more info about your configuration?

A Z420 has a 600W power supply by faceplate, but depending on exact config (processor, graphics cards, hard drives, etc) may only use as little as 130W even when operating at "peak" performance. Also, what other devices (such as monitors) are present?

Also, what are your goals for the UPS? i.e....
How much uptime do you need after the power outage?
Is your power grid often subject to brownouts or rolling blackouts where power conditioning features would be required in addition to blackout failover?

Re: Please Recommend a UPS for Z420

We use Back-UPS ES 750G on our Z820, works like a charm and give about 12 minutes of battery life.

Might be overkill for Z420, but it's not that expensive...

According to HP Quickspecs, a reference system with the same processor and RAM as you have will use, at most, 300W of sustained power when the system is at its most stressed.

Based on this, I'd recommend a 1000va UPS battery. That'll give you about 15 minutes of runtime, enough to save anything open and do a graceful shutdown.  You could use a 750va battery, but you'd get, at most, 7-8 minutes of runtime.  Keep in mind, too, that this runtime is when the battery is brand new, so it halves by about the 2.5 year mark.  That's why I recommend getting 1000va, so that in 2.5 years you'll be at 7 minutes as opposed to possibly under 3 minutes with a 750va.

To filter out occassional spikes in power, you'll want to ideally have a UPS that's at least line-interactive, if not online conversion of power. These features will ensure that the power fed to your system is filtered and kept at a constant sine wave.

Products I'd recommend would be in APC's "SmartUPS" product line, Cyberpower's "AVR" or "PFC" product lines, Tripplite's "Smart" product lines, or Eaton's "5S" and "5110" product lines.

I can't recommend an exact product because I'm not sure what country you're in (the part # of the workstation tells me you're not in the US, you're somewhere in the EMEA region), but if you call up any competent IT sales retailer in your region and tell them you want a 1000va line-interactive (also known as "automatic voltage regulation") UPS, you'll get what you need.

APC Back-UPS Pro 900VA (BR900GI)



Do you think it can c=comnfortably hold the charge for 10 minute on high load on this pc? (E5-1650 CPU)

Re: Please Recommend a UPS for Z420

You'll probably get about 10-12 minutes when the unit is brand new on a 900va battery.

 

Keep in mind that at 2.5 years, your life will be about half that (5-6 minutes).  If you want to maintain 8-10 minutes, you probably should replace the battery component of the UPS every 2 years.
