Tools
Free PC tools, each one built to settle a single question
6 tools, no sign-up, no email wall. Each card below says what the tool answers, who it is for, and what it will not do, so you can pick the right one without opening three of them first. They run on the same research and the same catalogue as our reviews.
VPN Streaming Checker
Will my VPN actually get into Sky Go, iPlayer, ITVX or Channel 4?
A verdict per VPN per service, taken from what each provider publishes, with the source and the date we last read it. It is not our own streaming test, and every row says so.
- For
- UK viewers abroad, and anyone whose VPN stopped working last week
- Serves
- “does nordvpn work with sky go”
PSU Calculator
What wattage power supply does my build actually need?
Pick your parts and get a wattage sized against transient spikes rather than average draw, plus what it costs to run per year at UK electricity prices and which units in stock fit.
- For
- Anyone speccing a new build or upgrading a graphics card
- Serves
- “what psu do i need”
GPU and PSU Checker
Is the power supply I already own enough for that graphics card?
Judges the supply you have against both the steady load and the millisecond spikes that are what actually trip an undersized unit, then tells you the size to buy if it falls short.
- For
- Upgraders dropping a new card into an existing machine
- Serves
- “is 650w enough for a 4070”
VPN Finder
Which VPN suits what I am actually trying to do?
A couple of plain-English questions about your situation, then a recommendation with the reasoning shown. No scores out of ten, and no pretending one provider wins everything.
- For
- First-time buyers who do not want to read six reviews first
- Serves
- “best vpn uk”
CPU Cooler Picker
Which cooler can handle my processor, and will it fit my case?
Filters the air and all-in-one coolers from our reviews down to the ones rated for your chip and short enough for your case, so clearance rules out the wrong answer before price does.
- For
- Builders whose stock cooler is loud, or whose chip is throttling
- Serves
- “best cooler for 14700k”
Data Recovery Checker
Are my deleted files still recoverable, and what should I do right now?
Walks through what happened to the drive and gives you an honest read on the odds, whether software can do it, and when to stop and call a lab before you make it worse.
- For
- Anyone who has just lost files and is about to try something rash
- Serves
- “recover deleted files windows”
How these tools work, and what they will not do
Every tool here runs on a small piece of shared logic rather than on a page of its own arithmetic. The same code that sizes a power supply on the calculator sizes it inside a graphics card review, so the two surfaces cannot quietly disagree about the same build. Where a figure comes from a manufacturer specification we say so, and where it comes from our own catalogue the date is on the page.
What they will not do is pretend to certainty they have not got. The streaming checker reports what each VPN provider publishes rather than claiming we streamed it ourselves. The power tools size against transient spikes, which is a modelled peak and not a measurement off a bench. When we do not hold the figures for a part, the tool says nothing instead of borrowing a number from a similar part, which is why some pages carry no tool at all.
They are free because the recommendations underneath them link to products we may earn a commission on. That never changes which product comes out on top: the ordering rules are the same whatever the commission looks like, and they are written down in how we review and how we score.
Once you have your answer
A number on its own does not buy anything. These are the pages the tools hand off to.
